UNITED STATES WILLIAM W. HUMMEL, OF FLOYD, IOWA.

SEALER.

Application filed. December 8, 1922. Serial No. 605,666.

To all whom it may concern:

Be it known that I, \VILLIAM W. HUM- MEL, a citizen of the United States, residing at Floyd, in the county of Floyd and State of Iowa, have invented new and useful Improvcments in Sealers, of which the following is a specification.

This invention relates to a jar wrench, the general object of the invention being to provide means for placing a cap upon a jar and to remove the cap therefrom.

Another object of the invention is to provide means for pressing the cap into lirm contact with the rubber gasket to insure an air tight closure of the jar.

lhis invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il lustrated in the accompanying drawings and speeilieally pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views. and in which Figure l is a plan view of the device.

Figure 2 is a side view with the parts in one position.

Figure 3 is a similar view with the parts in another position.

Figures -l, 5 and 6 are detail views.

In these views 1 and 2 indicate a pair of plates which are connected together and to a cam plate 3 by a pin 4. This pin passes through a slot 5 in the plate 2 so that said plate 2 has sliding movement in relation to the plates 1 and 3. A small projection 6 on the plate 1 extends into a slot '7 in the plate 2 to limit the sliding movement of said plate 2 and also to prevent rotary movement of the plate 2. The plates 1 and 2 have inelined side edges and their outer edges are rurved and bent over to form gripping jaws S fol engaging the cap of the jar. The plate 2 has its small inner end bent over to form a groove 9 to receive the edge of the ram plate 3. This cam plate is provided with holes 10 for receiving a pin 11 which is pivotally carried by the handle 12, said handle being pivoted to a channel part 13 which is pivoted in place by the pin 4. Thus by turning the handle to a position where the pin 11 can engage one of the holes 10 in the cam plate, said plate can be moved to cause its cam part to engage the groove 9 so as to force the plate 2 inwardly and thus cause the jaws 8 to grip the cap and thus lock the device to the cap. A large pro ec tion 14 is carried by the handle, said projection being oppositely arranged to the pin 11 so that after the jaws are caused to grip the cap the handle is swung over to place the rounded end of the projection against the flange of the cap and then by rotating the handle the flange of the cap Will be pressed into firm engagement with the gasket so as to make a tight joint. In this operation the channel member 13 simply rotates on the pin without moving the jaw parts. \Vhen the cap is to be tightened or loosened the handle is moved to a position where the pin 11 will engage one of the holes 10 so that the jaw plates will. be caused to move with the handle and as the jaws are in firm engagement with the cap, said cap will be caused to move with the device. The projection M can be used for breaking the seal on jars that have been sealed for some time so that the cap can be easily removed.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is A device of the class described comprising a pair of jaw plates, each provided with a curved flange on its outer edge, a pin and slot connection between the plates, the small end of one plate having a tongue thereon and the other plate having a slot therein. for receiving the tongue and the inner end of the other plate being curved to produce a groove, a cam plate held to the grooved plate by the pivot pin and having its cam part arranged to engage the groove, a channel-shaped member held on the cam plate by the pivot pin, a handle pivoted to the channel-shaped member and a projection thereon for engaging part of the cam plate to rotate the same.

In testimony whereof I aflix my signature.

WILLIAM W. HUMMEL.
